Artificial Kitaev chains, formed by quantum dots coupled via superconductors, have emerged as a promising platform for realizing Majorana bound states. Even a minimal Kitaev chain (a quantum dot-superconductor-quantum dot setup) can host Majorana states at discrete sweet spots. However, unambiguously identifying Majorana sweet spots in such a system is still challenging. In this work, we propose a

Addressing intertwined crises of climate change and biodiversity loss is a pressing global challenge, with trees playing pivotal roles in promoting carbon sequestration and habitat diversity. However, there is a distinct knowledge gap concerning the global drivers shaping tree cover and its heterogeneity, particularly the roles and relative importance of large herbivores and fire compared to clima

We experimentally explore the role of institutions imposing collective sanctions in sustaining cooperation. In our experiment, players only observe noisy signals about individual contributions in finitely repeated public goods game with imperfect monitoring, while total output is perfectly observed as it is often the case in collective action problems in society. We consider sanctioning mechanism

This article examines nuclear imaginaries in the Arabic-speaking Middle East. It situates people from the Arab world into nuclear thought, looking at how the atomic age rapidly became part of everyday lives. Embracing the idea that reality and fiction are not only deeply intertwined but also co-constitutive, it analyses everyday engagements with the nuclear condition in the aftermath of the bombin

Norrbotten region is one of the most sparsely populated areas in Europe, with often long distances to services. This paper aims to gain a deeper understanding of the everyday mobilities in later life in rural areas, and to assess to what extent digital service solutions (DiSS) can contribute to reduced accessibility poverty. The study focuses on how DiSS contribute to more equitable accessibility

BACKGROUND: The significant role of long non-coding 7S RNA in controlling mitochondrial transcription highlights its importance in mitochondrial function. Considering the suggested connection between mitochondrial dysfunction and the onset of mental disorders, this study aimed to explore the potential involvement of 7S RNA in the context of depression/anxiety.RESULTS: A total of 181 patients in pr

Aims: Infections are proposed risk factors for type 1 diabetes in children. We examined whether a diagnosis of infectious disease also confers an increased risk of latent autoimmune diabetes in adults (LADA). Materials and methods: We used data from a population-based Swedish case-control study with incident cases of LADA (n = 597) and matched controls (n = 2386). The history of infectious disease

How can live-performed chamber operas be conceptualized as immersive games with interactive features? This artistic study has resulted in a system model through which degrees of immersion may be generated and analyzed from physical, social, and psychical stimuli. A differentiation of immersive modes has been made possible by the framing of opera-making as game design. The findings indicate that so

Amyloid β peptide (Aβ) is the crucial protein component of extracellular plaques in Alzheimer’s disease. The plaques also contain gangliosides lipids, which are abundant in membranes of neuronal cells and in cell-derived vesicles and exosomes. When present at concentrations above its critical micelle concentration (cmc), gangliosides can occur as mixed micelles. Here, we study the coassembly of th

Animal offerings made at various sacred sites were an integral part of the ethnic religion of the indigenous Sámi people of northern parts of present-day Norway, Sweden, Finland, and Russia from ca. 800 AD onwards. The offering tradition was interwoven with subsistence patterns and human-animal relationships, as in the Sámi worldview offerings were a means to communicate with gods and guardian spi

This study brings a systematic review that evaluated 43 articles on Nature-Based Solutions (NBS) applied to stormwater management in urban areas. This review aims to establish a reference on NBS effectively applied and whose environmental, social, and economic benefits have been duly discussed. The results address 13 NBS techniques/methodologies implemented and their ecosystem benefits. Our findin

We study a Dirichlet boundary problem related to the fractional Laplacian in a manifold. Its variational formulation arises in the study of magnitude, an invariant of compact metric spaces given by the reciprocal of the ground state energy. Using recent techniques developed for pseudodifferential boundary problems we discuss the structure of the solution operator and resulting properties of the ma

Background The efficacy of the interception and purification mechanism for low-dose toxic contaminants in riverbeds, which serve as a link between surface water and groundwater, is of paramount importance in ensuring groundwater safety, particularly considering the replenishment of reclaimed water. The specific objective of this work is to identify the variation of interception efficiency and tran

The authors take on a problem that many departments in Sweden, not least in the humanities, are dealing with right now: language. They show how social status in academia is decoupled from linguistic integration, at least if we understand status in terms of academic titles. Feelings of insufficiency and incompleteness are, however, prevalent, even among those whose Swedish proficiency is objectivel

Objective: We tested the diagnostic accuracy of previously proposed magnetic resonance imaging (MRI) osteoarthritis (OA) definitions in a cohort after acute anterior cruciate ligament (ACL) injury. Methods: We studied participants with posteroanterior and lateral knee radiographs and MRI 5 years after ACL injury, scored using the Anterior Cruciate Ligament Osteoarthritis Score. Radiographic OA (RO

BackgroundHemolysis is a cardinal feature of hemolytic uremic syndrome (HUS) and during hemolysis excess arginase 1 is released from red blood cells. Increased arginase activity leads to reduced L-arginine, as it is converted to urea and L-ornithine, and thereby reduced nitric oxide bioavailability, with secondary vascular injury. The objective of this study was to investigate arginase release in

We present a novel class of minimax optimal control problems with positive dynamics, linear objective function and homogeneous constraints. The proposed problem class can be analyzed with dynamic programming and an explicit solution to the Bellman equation can be obtained, revealing that the optimal control policy (among all possible policies) is linear. This policy can in turn be computed through
